Finding Cowboys pocket schedules from the early 1960's can be a tough task. If you're lucky enough to find someone willing to sell, be prepared to pay a premium. Starting in the early 70's, KRLD 1080 (the Dallas area radio station that broadcasts Cowboys games) became the main sponsor for Cowboys schedules, taking over for Braniff. Several area companies used the schedules for advertising, adding their company name on the back. The complete list of all known sponsor variations can be found in The Dallas Cowboys Vintage Football Card & Memorabilia Guide.
